If you move Saldana outside of the ring of runes towards the entrance to the room, you can effectively avoid having to the kill Espíritu profanado throughout the encounter and focus all DPS on her. You will have to dodge Hoja de la aflicción when they spawn, but the range for each is only 4 yards, so it is easy to avoid.Espíritu profanados are adds that walk slowly towards the boss during Comunión oscura, and will heal and buff the boss if they reach her before her channel of Comunión oscura is complete (it is 20 seconds long). If the add DOES NOT reach her by the end of the cast, it despawns!

Position a player inside the circle of runes to be positioned to deal with the add when it spawns.

During Devastación del Vacío, when purple pools spawn all over the ground and must be avoided, the use of the reflective abilities can put a MASSIVE DoT on the boss, thus shortening the encounter significantly.

To execute this, when Ritual de huesos starts, the shaman should use (or the hunter use Disuasión) and then that player should STAND IN the purple ground effect behind the Ritual de huesos skeleton. This will reflect the damage onto that add, thus clearing a space for your group WITHOUT even attacking it at all! Keep in mind that the add will take a few seconds to die, as it needs to take a couple ticks of damage.
